Sigma 50mm f/2.8 EX DG Macro Lens for Canon SLR Cameras

Sigma launched its first standard 50mm macro lens in 1990, and followed it up with an improved model in 1998. The advent of digital SLR cameras, however, required updated optical technology and a better imaging performance. Enter the latest incarnation of the 50mm macro lens, with an improved design that corrects for various aberrations. Designed exclusively for Canon SLR cameras, this macro lens is specially coated to get the best possible color balance while cutting down on ghosting caused by reflections from the digital image sensor. The lens also includes a floating focusing system, which allows you to precisely photograph objects throughout the entire focusing range. Most importantly, this standard macro lens makes it possible to enjoy better communication with your subject. When viewing through the camera's finder, you'll be able to move the subject and make precise adjustments.

Customer Feedback :
The lens is an excellent lens for close-up photos. I am not a professional photographer but I try really hard to get good sharp photos. This lens will do the job.
Since it is also also a 50mm lens I have used it as a normal lens. The only problem with that is that over the years many of us have been spoiled with zoom lenses. With a zoom lens you can stand in one spot and zoom the lens in or out to get closer or father from your subject. With just the 50mm capability of this lens you have to physically move in or out to get a closer shot or a wider shot. This is not necessarily a criticism, just a comment about how we have been spoiled by zoom lenses.
I do not believe you will be disappointed with this lens. The price is great for the quality.
